Tetraism Calendar

Tetraism Calendar for Garmin is a Connect IQ watch app that brings an alternative calendar system to Garmin smartwatches and fitness devices. The app displays both the Tetraism calendar—a novel time-tracking system—and the traditional Gregorian calendar side-by-side, enabling users to track dates across both systems simultaneously. With intuitive month navigation and a custom-designed calendar grid interface, the app provides seamless access to dual calendar views on your wrist. The application supports a comprehensive range of Garmin devices, from sports watches like the Forerunner and Fenix series to outdoor navigation devices like the GPSMAP and eTrex Touch, ensuring broad compatibility across the Garmin ecosystem. Built with Connect IQ's native MonkeyC language and optimized for API level 1.2 and higher, the app delivers a lightweight, responsive experience tailored to the constraints and capabilities of wearable devices. The project features a custom launcher icon with a refined calendar grid design incorporating Tetraism visual accents, providing users with immediate visual identification on their device home screen.
